Before buying a laptop, you have to make a list of the things or requirements you need in a laptop. Some basic tips you remember before buy it:-
First of all set your budget for buying laptop and then decide which operating system you want to operate like iOS, Windows, Linux . And then search all top laptop brands on google.
After this you must check its Internal Memory or ROM which have to be minimum 500 GB but as my recommendation it should be 1 Tera Byte. RAM of the laptop should be 8 GB(recommended) so laptop can operate large software or big sized games easily. If you wanna play high graphics games then also prefer NVIDIA GeForce Graphic card so you can play games like GTA 5, Sniper Elite 4, FIFA etc.
Intel processors are excellent processors and in these processors prefer Intel core i7(recommended) or i5(minimum). The screen size must be 15.6 inch minimum and it resolution should be 1920x1080 pixels and it does have 3000+ nit brightness so your eyes doesnt fatigue after long use. Prefer genuine windows in laptop so in any case the windows gets corrupted youll have your backup.
There are some other features like its speakers, USB 3.0 ports, Projector ports, HDMI ports which should also have in it.
So guys with these tips, you can buy a amazing laptop. Thank you.
